*MA'CHINE FOR MAKING BUCKLES.

SPECIFICATION forming part of Letters Patent No. 339,899, dated April 13, 1886.

Application liled March 1. 18H6.

To @ZZ whom, it may concern:

Be it known that I, JARVIS E. KELSEY, of West Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Machines for Making Buckles 5 and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l, a top view of the apparatusbelow the upper die, Gv; Fig. 2, an under side view of the upper die, G; Fig. 3, a vertical section of the lower die cutting through one of the recesses b, and showing aside View ofthe upper die and of the follower M; Fig. 4, a front View of the lower die, showing the recesses b b; Fig. 5, the frame as bent preparatory to the operation of this apparatus; Fig. 6, au end view ofthe frame, showing the first operation; Fig. 7, lthe same, showing the second operation of this apparatus; Fig. 8, an end view ofa buckle complete; Fig. 9, a face View of the buckle complete.

This invention relates to an improvement in apparatus for manufacturing that class of buckles in which the frame is made from a piece of wire bent into nearly U shape, the tongue portion, also made from a single piece of wire bent to forni a loop in the central portion, and the two ends turned therefrom to form the tongues, the two ends of the frame bent around the tongue portion to forni the hinge between the two parts, the buckle being well known as the Hartshorn77 buckle, the invention being adapted to the manufacture of the frame part of the buckle.

In Fig. 5a single frame is shown as bent preparatory to the operation which it is proposed to perform by this invention. This is made from a piece of wire bent to form the bearing-bar A, turned at its two ends to form the roundedends B B of the frame, the end portions C C turned therefrom at right angles to the bearing-bar A, and distant from each other less than the extreme length of the frame. The two legs C C are to form the hinge portion of the frame, and are bent around the tongue portion.

Serial No. 193,595. (No model.)

The object of this invention is to strike the frame, and so as to flatten and shape the bearing-bar, as indicated in broken lines, Fig. 5, and to bend the legs into shape to be readily clasped upon the tongue portion, such shape being indicated in Fig. 7, and so that when the hinge is completely formed, as seen in Figs. 8 and 9, the tongue portion will be in substantially the plane of the frame; and the invention consists in the construction of the apparatus whereby the frame is shaped, as hereinafter described, and more particularly recited in the claim.

The apparatus is arranged in a coninion power-press, and in the illustration I show only the bed l) and the slide E of the press, it being understood that the bed is stationary, and the slide actuated in the usual manner, to reciprocate toward and from the bed, the mechanism for operating the slide being too well known to require illustration. On the bed a die, F, is fixed below the slide. The upper surface of this dicis plain andliat, except at the front or forward edge is a raised rib, c.

The rib is of a rounded shape, corresponding to the bend required in the legs ofthe frame. In the front of the die two cavities, b b, are made directly below the rib a, and so that the rounded shape of the rib continues into these recesses. The recesses are distant from each other corresponding to the legs of the frame to be bent, and so that as the frames are successively passed forward ont-o the die, as illustrated in Fig. l, the two legs C C of thc frame will project over the rib a, and at points corresponding to the recesses b b in the front of the die, as indicated in Fig. 3.

G is the movable die, which is fixed in the slide Ein the usual manner. Longitudinally across its under face is a recess, e, correspond ing to the exterior-of the bend required in the legs, and forward of the recess the die projects downward, as at f, below the face of the die G. On the face of the die C a cavity is formed, as indicated in Fig. 2, corresponding to the finished shape of the body part of the frame, and ofthe usual shape for this class of buckles.

Vhen the frame isplaced upon the lower die, with its legs projecting over the rib a, as seen in Figs. 1 and 3, the slide descends, bringing the die G down upon the frame, the recess IOO e causing the body of the frame to come down upon the face of the die F, back of the rib a, and the projection f turns the legs straight downward. This operation shapes the body of the frame and brings the legs into the shape indicated in Fig. 6, the bend of the legs being above the plane of the frame. As this bend is made, the two legs stand forward of the reeesses b b below the rib. l

During the last part of the descent of the slide E a horizontal slide, H, is actuated by the slide E-say as by a cam, I, fixed to the slide E-acting upon the slide H., through a post, L, thereon, and so that an inward movement is imparted to the slide H `during the said last part of the descent of the slide E. The slide H carries a follower7 M, in the plane vfof the recesses b b in the front of the die F, and so that as the follower M advances, under the movement of the slide H, two projections, 71 on the inner end of the follower M will impinge upon the downwardly-projecting portion of the legs of the frame and bend them into the recesses b I), as indicated in broken lilies, Fig. 2, and complete the bend of the' legs, as shown in Fig. 7. By this operation the frame is shaped and the hinge portion of the legs bent into a convenient shape to be turned around the tongue portion, as indicated in Figs. 8 and 9, and such bend being both above and below the plane of the frame, brings the.

responding to the rib a, and also with a down-k ward projection, f, forward of saidl recess e, with the horizontally-reciprocating follower BL constructed with projections h h, corresponding to said recessesin the front of the die F, substantially as and for the purpose described.
